在我的应用程序中，我使用flutter_local_notifications: ^1.4.2插件进行本地通知。用户选择要安排alarm的工作日，并且在保存时，我将alarm对象传递给setSchedulerNotifications方法，以在警报的repeatWeekdays列表中设置每天的通知。我循环查看repeatWeekdays列表，并在每个循环中设置一个通知，其id为传入的警报id+循环编号，为增量。到目前为止，一切如预期。
现在，当警报被编辑时(不同的时间(，在保存时，我将新警报传递给modifySchedulerNotification方法，该方法首先调用deleteSchedulerNotifications方法(具有相同的循环来计算通知id(，然后再次调用setSchedulerNotifications。
打印显示setSchedulerNotifications中的通知ID是正确的，并且在deleteSchedulerNotifications和第二个setSchedulerNotifications调用中是一致的，但当设置第二次(与第一次相同的ID(时，通知不会在新时间激发，而是在旧时间激发。
你能发现我做错了什么吗？
通知方式：
Set
Future<void> setSchedulerNotifications(Alarm alarm) async {
print(
'##### LocalNotificationRepository().setSchedulerNotifications called');
print('##### sound to play is : ${alarm.sound.toLowerCase()}');
for (int i = 0; i < alarm.repeatWeekdays.length; i++) {

'Scherduled checking for route ${alarm.alarmName}';
String sound = alarm.sound.toLowerCase();
DateFormat dateFormat = DateFormat('HH:mm');
var date = dateFormat.parse(alarm.time);
int hour = date.hour;
int minute = date.minute;
Time time = Time(hour, minute, 0);
var androidPlatformChannelSpecifics = AndroidNotificationDetails(

删除
Future<void> deleteSchedulerNotifications(Alarm alarm) async {

for (int i = 0; i < alarm.repeatWeekdays.length; i++) {
int id = int.parse(alarm.alarmId) + i;

}).whenComplete(() {
print('@@@@ Deleted local notification with id: $id');
print('@@ LocalNotificationRepository().deleteWeeklyNotifications()n'
'@@ all notifications for this route check are deleted');
// return;
});
}
}
修改
Future<void> modifySchedulerNotification(Alarm alarm) async {
print(
'## LocalNotificationRepository().modifyWeeklyNotifications() calledn'
'## for alarm ${alarm.toMap().toString()}');
await deleteSchedulerNotifications(alarm).whenComplete(() async {
print('## LocalNotificationRepository().modifyWeeklyNotifications()n'
'## old notifications for alarm ${alarm.toMap().toString()} have been deleted.n'
'## are there new notifications to be set? ${alarm.enabled}');
if (alarm.enabled == true) {
await setSchedulerNotifications(alarm).whenComplete(() {
print('## LocalNotificationRepository().modifyWeeklyNotifications()n'
'## new notifications for alarm ${alarm.toMap().toString()} are set');
return;
});
}
});
print(
'modifyWeeklyNotifications() all notifications for this route check are modified');
}

终于找到了错误。。我正在将旧的Alarm对象传递给modifySchedulerNotification方法。
